To all whom it may concern:

Be it known that I, WILLIAM W. Rosan- FIELD a citizen of the UnitedStates, residing I in the borough of Manhattan, in the city, count andState of New York, have invented an mprovement in Phonographs, of whichthe following is a specification.

This invention relates to automatic return mechanisms for phonogra hs.

A full understanding of the invention'can best be ivenby a detaileddescription of a preferred ousfeatures thereof, and such descriptionwill now be given in connection with the accompanying drawings, showingsuch a pre; ferred construction.

In said drawings, Fi re 1 is a plan view df a phonograph provided 'vllith automatic return mechanism embodyin my invention. Fig. 2is anelevation of t e return mechanism with the auxiliary or return feed-shart broken away, 'so as to moreelearly show other parts. Fig. 3 is'asection taken on the line a: a: of Fig. 1 looking toward the left, andFig. 4 is a section taken on thel'nie y y of Fig. 1 looking toward theleft, arts bein omitted from Fig. 3 forclearn/cssw ch are a own in Fig.4.

0 represents the usual bed of a honograph or sinnlrarmachine; b, thethreade feed-shaft b ,the mandrel, which is shown as carried by bearingsfor the feed-shaft 2 the driving-pulley for the back frame a carries ausual construction, to the which is secured the recarrier e, and 5 is arest for and mandrel, and feedshaft. The

slidin sleeve 11 of right-hand end of producer arm or porting the sameas it makes its re roducing movement. In the drawings I ave not shownthe reproducer 'roper, but only the annular carrier adapt to receivethesame. The sleeve d also carries a feed-arm (1', provided with a threadedblock of usual construction to mesh with the thread of the feed-shaft b,so that in the usual manner movement is communicated from the shaft bthrough the feed-arm d to the sleeve 11 and to the reproducer-arm e,causing the same to move longitudinally of the record on the mandrel b.The parts above described are or may bc-of usual construction. a is aswinging arm of usual form.

An auxiliary shaft-f, which serves as a rcturn fecd -shaft, is providedwith a spiral groove or scrcw-thread 7 and has a portion constructionembodying the varif of its surface between the convolntions of thespiral groove at or near its right-hand end provided with teeth 8 and ismounted in earingsf'ff on an auxiliary bed or late adapted to rest uponand be secure to t o bed a. The right-hand end of the shaft f is reducedto pass into the bearin left-hand end of the shaft is of ulhsize andpasses through the bearingjfiand upon the end of the shaft adjacent tothis latter hearing is a ear 4, meshing with a gear 3 on the feed-she tb. To prevent the auxiliary shaft from moving out of its bearin thelefthand bearing f is provided wit a screwstud ,19, which carries'a disk20, which overlaifis' the gear 4 to prevent longitudinal move- ,ment ofthe auxiliary shaft. An eccentric cam g, 'havinq mounted on thcanxiliaryshaft, so as to be adjustable longitudinally thereof, beingsecured inposition by means of a set-screw, as shown in Fig. 2. Fig. 4 shows theeccentric shape of the cam, and Figs. 1 and 2show the spiral formthereof.

A bracket his secured to the sleeve (1, as by means of an arm h, splitand clamped to the sleeve by means of a screw, as shown in Fig. 3. Thebracket It carries a bar 9, having a flat facc, said bar extendingthrough an opening in the bracket and parallel with the auxiliary shaftf, bcingadjustable lengthwise and sccnrcd in any dcsircd position of itslcngthwiscadjustmcntbymcnnsol'nscrcw15. An eccentric segment i isrotntubly mounted on the right-hand cud of the bar 9, its rota movementbeing limited, as by marine of the pin 14, which engages the cut-awayend of the hub of the segment, and the segment is normally held in theposition shown in the drawings by means of a helical spring 11, one endof which -is secured to the segment and the other end to a collar or hubin, fast on the'bar 9. The greater portion of the K!- riphery of theeccentric segment is provii cd with teeth 12, and the portion of theperiphery beyond the teeth at the end of greatest rarius forms atail-rib 13. Extending from the face of the eccentric segment is acum-plate i, the outer edge of which is at an inclination to the axis ofthe bar 9. This cam-plate is adapted to engage an abutment formed, asshown, by a post 6, having a horizontal portion which passes through apart of the hearing f and is adjustably secured by means of a set-screwto rovide for ad 'ustmeat of the post longitudipally of the irection ofmovement of the segment i. The

f, mania a spiral rib or shoulder, is

mally in position with a rearward extension thereof against a stop-pin18. The forward end of the arm 1c is provided with adownwardly-projecting stud k for engaging the eccentric'spiral cam g.

The operation is as follows: The bracket 71, carrying the eccentricsegment 'i and arm It, moves with the sleeve (1 and reproducer-arm e'asthe reproducer makes its reproducing movement, the eccentric segmentbeing at this time held by the spring 11 in its normal position, asshown in the drawings. As the reproducer draws near the end of therecord the cam-plate 11' comes into engagement with the post (5, so thatas the movement continues the eccentric segment '5 is turned to bringits teeth 12 into engagement with the teeth 8 of theauxiliary or returnfeed-shaft. The segment is then further turned or rotated by therotation of the auxiliary shaft and its toothed periphery caused to proressively engage the toothed surface of the shaft until the tail-rib 13is brought into position to enter the groove 7 of the auxiliary shaft.This turning movement of the eccentric segment because of the eccentricor cam form of the segment raises the bracket h, and thereby rocks thesleeve d and elevates the reproducerarm 0 to move the point of thereproducer off the record and elevates the feed-arm d to disengage itsthreaded block from the shaft 6, thereby interrupting the forward orreproducing movement of said parts. The tail-rib 13 being then broughtinto position to enter the groove of the auxilia shaft and the rotationof the auxiliary s aft continuing, a reverse movement is imparted to thebracket h, sleeve d, reproducer-arm, and feed-arm, said parts thenmoving toward the left in Fig. 1, and this movement is secured withoutnecessitating anysto page or change in direction of rotation of theeed-shaft b. The rotation of the auxiliaryshaft f is in a directionopposite to the direction in which the spring 11 tends to move theeccentric segment t to return it to the position shown in Fig. 3.Consequently the rotation of the auxilia shaft ,while causing the returnmovemento the parts, tends to keep the eccentric segment in positionwith its tail 'rib 13 in the groove of the shaft, the weight of thereproducer-arm and feed-arm being at this time supported by theeccentrio segment and tend mg to increase thehf'fictiou hm ween thetail-'rib l3 and the auxiliary shalt As the parts approach the extremeleft-hand end of their return movement, the

stud k of the arm is ('u'|11( into engagement with the eccentric spiralcam g, and if a high part of the cam is uppermost the arm 1: yieldsuntil a low point of the cam gthat is, a point near the surface of theauxiliary shaftcomes opposite the stud 7c. When such low point of thecam is opposite .the stud 7c, the stud moves over the surfabk of thecam, and as the cam continues its rotary movement it will by engagementwith the stud is cause a further elevation of the bracket h, whereby theeccentric segment will be raised to clear the auxiliary shaft. When theeccentric segment is thus raised out of engagement with the auxiliaryshaft, it will be returned by the action of the s rin 11 to its normalposition, (shown in the frawings) and then by the continued rotation ofthe cam g the bracket It will again be lowered, and at the same timestud k, coming into engagement with the spiral shoulder or rib of thecam, will be run off the cam and the parts will return to osition, withthe threaded block of the fee -a.rm dt in en agement with the feed-shaftb and with t e reproduceragain in reproducing position, and the partsWlll be in position or another reproducing movement. The coaction of thecam-plate k i and post 6 and of the,teeth.-12 of the eccentric segmentwith the teeth8 of the auxiliary shaft effect a gradual operation uponand raising of the reproducer-arm e and the palfts connected therewith,gradual] bringing the tail-rib 13 into the groove Tier the returnmovement, and the coaction-of the arm k and its stud is under thecontrol of the spring 11 with the eccentric spiral cum 9 efiects astopping of this return movement anda adual lowering of thereproducer-arm and sadarm into position for another reproducingmovement. The adjustment. ovided for the eccentric spiral camlongitudinally of the auxiliary shaft f and t e ad ustment pro vided fort segment i, and for the bar 6 in the bearing is to adapt the mechanismfor records of varying lengths, so that the reproducing devices mayoperate only over the length 0 the actualrecord, and so that there maybeno time wasted or unnecessary distance traveled by the parts.

The invention provides an exceedingly simple mechanism positive in itsaction and efiicient and having no parts liable to get out of order.

It will be und rstoocl that theinvention is not to be limitvd to theexact constructions and arrangements of arts shown, and to which theforegoing escription has been mainly confined, but that it includeschanges and modifications'thereof within the claims. For example, I donot herein limit in self to the employment of the spring-control edarmA: or the )articular parts associated therewith, as t m stud 16 maylie-tightened and said arm be thus caused tooccupyafixed e bar 9,carrying the eccentric reproducing machines to which t 2. In aphonoposition and the eccentric cam g be' placed 1n accordance with such achange of the arm. Furthermore, some equivalent structure may be used inlieu thereof without departing from my invention.' It will be understooalso that the, term phonogra h is used herein as a broad term to inclu call soundhe invention is or may be found applicable.
